This page documents common bugs in Fedora 29 and, if available, fixes or workarounds for these problems. If you find your problem in this page, do not file a bug for it, unless otherwise instructed. Where appropriate, a reference to the current bug(s) in Bugzilla is included.

Release Notes

My bug is not listed

Not every bug is listed in this page, but Bugzilla should be a comprehensive database of known bugs. This page is a sampling of the bugs most commonly discussed on our mailing lists and forums.

To see if your bug has already been reported, you can search Bugzilla. If it has not yet been reported, we encourage you to do so to help improve Fedora for yourself and others. A guide to Bugs and feature requests has been prepared to assist you.

If you believe an already-reported bug report should be added to this page because it is commonly encountered, you can:

Add it yourself, if you have wiki access. Common_bugs_instructions provides guidance on how to add an entry to the page correctly, but the most important thing is to make sure that the bug is listed - don't worry if you don't get the format quite right, we can clean it up later.

Or, add the CommonBugs keyword to the bug report. Someone from the QA team will then inspect the issue to determine whether the bug should be listed as a common bug. To expedite your request, please add a comment to the bug that includes

a summary of the problem

any known workarounds

an assessment on the impact to Fedora users

For reference, you can query Bugzilla for bugs tagged CommonBugs:

Installation issues

UEFI install in 'basic graphics mode' may fail to boot

Several testers have reported that attempting to boot Fedora 29 installer images in native UEFI mode and using the Install Fedora 29 in basic graphics mode option from the Troubleshooting menu may fail to reach the graphical installer successfully.

So far, this bug has not been reported to affect any system which does not boot successfully using the regular boot option, so we suggest simply doing that instead. If you have a system which fails to boot either in "normal" or "basic" graphics mode, please report this to the bug.

Switching keyboard layout with key combo does not work in Wayland on Fedora Workstation Live image

If you're running Workstation Live install media and configure multiple languages in the installer, you won't be able to switch between them using the standard system shortcut (typically ⊞ Win+Space or Alt+⇧ Shift). However, you can still click on the language indicator in the installer with the mouse and that will switch the languages.

This does not affect other install media (KDE Live, DVD and netinst images).

no "install to hard drive" icon in soas, add to "get fedora" webpage to switch to sugar-terminal and enter "liveinst" to start installer

Core system issues

Cron jobs in /etc/cron.d (including cron.hourly) do not run

Testing has shown that cron jobs in correct formats dropped into /etc/cron.d do not get run. This includes all scripts dropped into /etc/cron.hourly, as execution of those depends on a job in /etc/cron.d. This problem is due to SELinux blocking the operation.

To work around this problem until it is resolved, a comment on the bug report contains a suggested CIL-formatted policy that allows these jobs to run:

(allow unconfined_t system_cron_spool_t( file ( entrypoint)))

to use this, save that single line to a file with the extension .cil, e.g. crond.cil, and load it with semodule, e.g. sudo semodule -i crond.cil. After you do this, the jobs should execute successfully.

DNF operations performed with modular repositories offline are not aware of modules

If you have any modules enabled on your Fedora 29 system, and you somehow perform a package management operation with the modular repositories disabled, any packages installed from the modules will be treated as if they were non-modular packages.

For instance, say you have a module enabled that provides version 2.0 of package foo, but the non-modular Fedora 29 repositories contain version 3.0 of the same package. Normally, when you run DNF, it will recognize that you are using the module, and not offer to upgrade to foo 3.0 from the non-modular repositories. If, however, you somehow run an update operation with the modular repositories disabled, DNF will incorrectly offer this "update".

It is not likely that you will run into this scenario in normal use of Fedora 29 Beta, but we do recommend you be careful with the use of the --disablerepo argument to DNF. It is also at least possible that you may hit it by temporarily enabling the updates-testing-modular repository to enable a new repository; until the module is present in the updates-modular repository, subsequent operations without the updates-testing-modular repository enabled may run into this issue, so, again, take care.

We are aiming to resolve at least the worst possible cases and consequences of this before Fedora 29 proper is released.

DNF doesn't resolve variables in mirrorlists

When a yum/dnf repository uses a mirrorlist link, and the content of this link contains URLs with special dnf variables, such as $releasever or $basearch, DNF is unable to replace them with correct release values and fails to download metadata from those links.

Such behaviour did not happen in previous version of Fedora and there is no workaround for it. A fix has been submitted to solve it. When it is found helpful, this issues will be solved in one of the future updates.

System update fails when trying to remove rtkit-0.11-19.fc29

This affects only Fedora 29 pre-release installations. If you have rtkit-0.11-19.fc29 in your system, an update to a later rtkit will fail, because the older version can't be removed. You can check what version of rtkit you have with this command:

$ rpm -q rtkit
rtkit-0.11-20.fc29.x86_64

If your base installation had at least rtkit-0.11-20.fc29, you should be fine. You can check whether you are affected by first fully updating your system, and then by running:

Package management tools (dnf, GNOME Software etc.) can crash when more than one runs at once

Note: We hope this problem has been fixed in the final Fedora 29 release and should no longer happen. In case you can still see it with a fully up-to-date system, see the description below and please provide your feedback in RHBZ #1631533.

The version of libdnf included in Fedora 29 introduces a database called 'swdb' which is intended to replace old, tool-specific databases like the yum/DNF history database, with the intention that all package management tools will share a common view of the transaction history and so on. However, it seems that multiple processes attempting to access this database simultaneously may not queue in an orderly fashion, or exit cleanly, but crash with an error message like Exec failed: database is locked. So far, this issue has been reproduced with one dnf process and one pkcon process, and also with two dnf processes.

To the best of our current knowledge, this problem cannot result in partially-completed transactions or inconsistent databases, as the process that crashes should not have actually made any changes to anything yet. However, as any crash in a package manager is undesirable and worrying, we are working to resolve this as soon as possible.

To "work around" it for now, simply retry the transaction that failed. Once the other transaction has completed, it should succeed. If the other process is one you ran yourself, it should be easy to identify, but it may be harder if it is an automatically-scheduled update or something along those lines.

Workstation (GNOME) Issues

Download progress is often invisible if GNOME Software

When you update your system with Gnome Software, sometimes the progress bar showing the percentage of downloaded packages is not correctly visible on the lower part of the Cancel button. This problem does not affect the functionality of the application and updating the system still works fine.

Note, that downloading the package set may take several minutes and the application may look unresponsive. If you see such behaviour, do not cancel the download process and wait until it is finished and you are offered to Reboot and Install.

Download button in GNOME Software performs the download, but then changes back to Download

Some testers experienced a situation, when, during system update via Gnome Software, they pushed the Download button and after the packages were downloaded, the button returned to a Download button again and the application did not proceed to Reboot and Update button. As a consequence, the system could not be updated.

If you arrive in that situation, the workaround is log out and back in again, or reboot the machine. After that, the application shows the Reboot and update button and lets you update the system.

Refresh button in GNOME Software doesn't refresh the repos

The Refresh button does not refresh the repository metadata in GNOME Software. A fix has already been submitted to upstream and once it is stable, the issue will be solved in a future update.

You don't need to work around this problem, because automatic refresh of repositories works fine, so you'll be offered updated packages regularly without issues. However, if you want to force GNOME Software to show you the latest updates immediately, execute this command:

$ pkcon refresh force

Previous update info is leaking into current update info in GNOME Software

When you update packages with Gnome Software, some of the previously updated packages are still shown in the update queue. This problem does not affect the functionality of the application and updating packages still works fine.

If you happen to see such behaviour, you can safely ignore it.

GNOME may crash on switch back from virtual terminal under X.org with multiple displays

Some testers have reported that GNOME may crash on a system with multiple displays, running GNOME under X.org (rather than Wayland), if the user switches to a VT (console) and then switches back again. So far this bug has been reported to affect Lenovo Thinkpad T460s, T470s and T480s laptops, and a desktop with a Radeon R7-based graphics card, with various display configurations.

If you are affected by a problem like this, the most obvious workaround is to run on Wayland instead of X.org, if you can. If you must use X.org, we can only advise that you avoid using virtual terminals until this can be investigated and resolved.

Switch user option missing from user menu until lock screen appears

Due to a bug, the Switch user option on the user menu (top-right menu, then expand the user name) in GNOME may be missing in any given session until the lock screen has appeared at least once. To work around this issue, you can trigger the lock screen manually. If the Switch user option still doesn't appear, you can switch to a different user from the lock screen itself, before entering your password there is a Log in as another user button.

Display gets messed up when routing panel is active in Gnome Maps

On some systems, when planning a route, Gnome Maps failed to render correctly. The routing panel on the right side of the map opens, but its content is incorrectly displayed and hidden behind a white unresponsive panel. Trying to resize the panel can only help occasionally, and sometimes it might lead to even a worse situation.

As a workaround for this behaviour, you can use an Xorg session instead of a Wayland session. To do so, click on the settings wheel in the login screen and from the list of options, choose GNOME on Xorg. This bug will be fixed in one of the future updates.

Running applications can lose data on log out from GNOME

If you log out from a GNOME session and have some GNOME applications running, these applications will not be terminated correctly which results in loss of data or settings, if those have not been saved before. In order to avoid any possible problems caused by this, you should definitely save any unsaved work and ideally close running applications manually before logging out.

There have been some less clear reports of applications not shutting down cleanly on log out from GNOME Xorg sessions, which is under discussion in bug #1394937, but we are not yet entirely sure about the details of that possible case.

Offline updates get stuck towards the end due to a libdnf crash when any multilib package is installed

When you perform offline updates in GNOME (reboot to perform updates), the process might crash at the very end of the process, seemingly hanging on a screen showing 97% or more percent done. We believe this most commonly occurs if you have any multilib package installed - i.e. packages of the same name for different arches installed together. This will often be the case if you run wine or some popular 32-bit third-party games and applications. If you see the percentage at 97 or higher and it does not update for half an hour or longer, force reboot using Ctrl+Alt+Del, the system should not be negatively affected in any way. The DNF team is currently working on a fix for this issue.

Totem and Cheese fail on Wayland in virtual machines

Totem (Videos) will fail to play media when using a Wayland session in virtual machines (applies to default libvirt VMs, but not VirtualBox). The audio will play, but neither video nor a totem window will appear. If you need to play media in this environment, please either use X11 session, or a different media player.

Cheese fails to start in a similar fashion. Because VMs usually don't have a webcam, this doesn't limit users in any way.

1Gb/s ethernet port is configured as 10Mb/s port on selected laptops

With kernel version greater than 4.15.0, some testers have experienced a significant drop in ethernet speed after unplugging and plugging again the ethernet cable on certain laptops. Originally, the were connected with a speed of 1Gb per second, which then dropped down to 10 Mb/s. Apparently, this only happen to affect the download speed and leaves the upload speed at its original value.

If you hit this problem, there are several ways to resolve this:

restart your system with your cable already plugged in (don't plug it in when your system is running)

run ethtool -r ETHNAME, where ETHNAME is the name of your ethernet device, possible to see e.g. in ip address output

ARM & AArch64 Issues

Raspberry Pi WiFI not working

Raspberry Pi WiFI issues on aarch64

A pair of regressions in the kernel included in the Fedora 29 GA release inadvertently caused the WiFi driver for Raspberry Pi devices to be intermittent. The issues have been resolved as of the 4.19.10 kernel.

Raspberry Pi config.txt is replaced during an upgrade from a previous release

When upgrading from a previous release on the Raspberry Pi 2/3/3+ the config.txt is replaced in the update process. To ensure any user defined settings are saved, please create a backup before upgrading. After the upgrade you will also need to re-enable the UART in config.txt if you intend to use the serial console.
